HARROW.

Specification of Letters Patent.

Application filed August 12, 1912.

Patented July 8, 1913. Serial No. 714,719.

To all whom it may concern Be it known that 1, JAMES Honor, a citi-.

zen of the Dominion of Canada, residing at A shl and, in the county of Ashland and State of WVisconsin, have invented certain new and useful Improvements in Harrows, of which the following is a specification.

This invention relates to harrows, and primaril to that class or type in which the cart i-pulverizing member is movably mounted.

The invention has for one of its objects the provision of a movable or reciprocating earth-pulverizing member in combination with a. stationary pulverizing member, either one of which is mounted in advance of the other one and adapted to operate on the soil in a longitudinal direction as well as a lateral one.

The invention also resides in the novel mounting of the several pulverizing or harrowing members whereby the latter may be elevated into an inoperative position for various reasons.

A still further object is found in the adjustability of the harrowing members whereby the teeth or spikes may be disposed in an angular position as well as a perpendicular one.

lVith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the present invention, parts of the wheeled body being omitted. Fig. 2 is a top plan view of the harrow disconnected from the wheeled body. Fig. 3 is a front elevation of the harrow. Fig. 4 is alongitudinal sectional view thereof taken on the line 4l of Fig. 2. Figs. 5 and 6 are elevations of the parts shown in Fig. 2, looking at opposite ends of the same. Fig. 7 is a cross sectional view taken on the line 7-7 of Fig. 2, the movable harrow member being omitted, and Fig. 8 is a. perspective view of the movable pulverizing member.

Throughout the following detail description and on the several. figures of. the drawings, similar parts are referred to by like reference characters.

In carrying out the present invention, the movable harrow member has imparted thereto a reciprocatory movement, such movement being given by a mechanism similar to that used in a mowing machine, while the harrow body is mounted in a pivotal manner, such as the mower sickle bars are.

The wheeled body, designated by A, is of ordinary construction, as above stated, and has the harrow body, designated by B, pivotally mounted on the frame C, the latter being supported bv the body A.

The harrow body B comprises spaced stationary earth-pulverizing members 1 which are supported by the runners or shoes 2 in such a manne as to permit angular adjustment of said members. Disposed between these members 1 is an earth-pulverizing member 3 reciprocatingly mounted and adapted to cross the paths of said members 1. Such movement is imparted to the member 3 by the pit-man a fastened to said member at 5, said pitman a being connected at its opposite end in an eccentric manner to a rotating wheel, not shown, in a manner similar to the pitman rod connection in the mowing machines now on the market. Carried by each shoe and intermediate the bearings of the members 1 is a pair of angularshaped guide members 6 adapted to receive therebeneath the flanges 7 formed on the terminals of the member 3, whereby the latter is guided in its reciprocatory movement. The central or spike-carrying portion of the member 3 is detachably fixed to the flanged terminals by collars 8 having a suitable number of set screws 9, as is most clearly shown in Fig. 4, to permit of angular adjustment of said central portion, as well as the removal thereof.

As above stated, the earth-pulverizing members 1 are limited against longitudinal movement, but are so mounted as to permit an oscillatory or angular adjustment whereby the teeth 1 may be moved toward or away from the teeth 3 of the movable pulverizing member. In order to operate the stationary members 1 and to retain the latter in a predetermined adjustment, a quadrant or toothed plate 10 is mounted on the outer shoe 2, said plate supporting in a pivotal. manner a lever 11 connected at its lower terminal by the links 12, the latter being pivotally connected with the upstanding ears 13 carried on Said members 1. foregoing, it will be noted that the members 1 may be angularly adjusted as well as the reciprocating member 3, whereby the combined advantages of the inclined and From the.

straight spiked harrows are obtained. Furthermore, it will be observed that in operation the reciprocating member 3 operates upon the earth in a lateral direction, breaking up the lumps of dirt which escaped the barrow member 1 disposed in advance of said member 3, and then after this operation, the rear member 1 levels the earth as well as gives it a final working.

A plurality of brace rods 1% are fastened to the harrow body for strengthening the latter. \Vhen it is desired to remove the harrow from the ground for transportation purposes, the latter may be swung upwardly on its pivotal connection 15 in a similar manner as the ordinary type of mower, as will be obvious. The harrow so constructed will be very efiicient in its operation, since the ordinary longitudinal movement of the teeth is obtained, as well as the additional lateral operation which easily pulverizes the earth to make the latter more fit for the cultivation of grain, vegetables, and the like.

Having thus described the invention, what is claimed as new is:

1.. A harrow comprising frame members, spaced angularly adjustable earth-pulverizing members thereon, a pulverizing member disposed between said spaced members and movable transversely of the frame members,

said movable member being angularly adjustable, and means for imparting movement to said movable member.

2. A harrow comprising frame members, a plurality of angularly adjustable earthpulverizing members, means for simultaneously adjusting said pulverizing members, and another earth-pulverizing member, said last mentioned pulverizing member being movable reciprocally. I

3. A harrow comprising spaced shoes, spaced angularly adjustable earth-pulverizing members mounted thereon, a'movably mounted earthpulverizing member disposed between said pulverizing members, means for imparting a reciprocatory movement to said movably mounted member, means for simultaneously adjusting the angularly adjustable members, and means for angularly adjusting the movable member.

In testimony whereof I affix my signature in presence of two witnesses.
